Sustained attention, a key cognitive skill that improves during childhood and adolescence, tends to be worse in some emotional and behavioural disorders. Sustained attention is typically studied in non-affective task contexts; here, we used a novel task to index performance in affective versus neutral contexts across adolescence (N = 465; ages 11–18). We asked whether: (i) performance would be worse in negative versus neutral task contexts; (ii) performance would improve with age; (iii) affective interference would be greater in younger adolescents; (...) (iv) adolescents at risk for depression and higher in anxiety would show overall worse performance; and (v) would show differential performance in negative contexts. Results indicated that participants performed more poorly in negative contexts and showed age-related performance improvements. Those at risk of depression performed more poorly than those at lower risk. However, there was no difference between groups as a result of affective context. For anxiety there was no difference in performance as a function of severity. However, those with higher anxiety showed less variance in their reaction times to negative stimuli than those with lower anxiety. One interpretation is that moderate levels of emotional arousal associated with anxiety make individuals less susceptible to the distracting effects of negative stimuli. (shrink)

We discuss our surgical philosophy concerning the subtle interplay between the size of the surgical margin taken and the resultant morbidity from ablative oncological. procedures, which is ever more evident in the treatment of head and neck malignancy. The extent of tissue resection is determined by the "trade off" between cancer control and the perioperative, functional and aesthetic morbidity and mortality of the surgery. We also discuss our dilemmas concerning recent minimally invasive endoscopic microsurgical. techniques for the trans-oral laser removal. (...) or co-ablation of aero-digestive tract tumours, which result in a minimal. surgical margin of oncological clearance. By a process of inductive argument as to the nature of the surgical margin, we consider whether the risks of taking a lesser margin with adjuvant therapy is justified by the attendant gain in reduced surgical morbidity and the possible costs in tumour control.

This introductory textbook presents Christian philosophical and theological approaches to ethics. Combining their expertise in philosophy and theology, the authors explain the beliefs, values, and practices of various Christian ethical viewpoints, addressing biblical teachings as well as traditional ethical theories that contribute to informed moral decision-making. Each chapter begins with Words to Watch and includes a relevant case study on a vexing ethical issue, such as caring for the environment, human sexuality, abortion, capital punishment, war, and euthanasia. End-of-chapter reflection questions, (...) illustrations, and additional information tables are also included. (shrink)

Much existing literature in anthropology suggests that teaching is rare in non-Western societies, and that cultural transmission is mostly vertical (parent-to-offspring). However, applications of evolutionary theory to humans predict both teaching and non-vertical transmission of culturally learned skills, behaviors, and knowledge should be common cross-culturally. Here, we review this body of theory to derive predictions about when teaching and non-vertical transmission should be adaptive, and thus more likely to be observed empirically. Using three interviews conducted with rural Fijian populations, we (...) find that parents are more likely to teach than are other kin types, high-skill and highly valued domains are more likely to be taught, and oblique transmission is associated with high-skill domains, which are learned later in life. Finally, we conclude that the apparent conflict between theory and empirical evidence is due to a mismatch of theoretical hypotheses and empirical claims across disciplines, and we reconcile theory with the existing literature in light of our results.

Understanding cooperation and punishment in small-scale societies is crucial for explaining the origins of human cooperation. We studied warfare among the Turkana, a politically uncentralized, egalitarian, nomadic pastoral society in East Africa. Based on a representative sample of 88 recent raids, we show that the Turkana sustain costly cooperation in combat at a remarkably large scale, at least in part, through punishment of free-riders. Raiding parties comprised several hundred warriors and participants are not kin or day-to-day interactants. Warriors incur substantial (...) risk of death and produce collective benefits. Cowardice and desertions occur. (shrink)

Much human adaptation depends on the gradual accumulation of culturally transmitted knowledge and technology. Recent models of this process predict that large, well-connected populations will have more diverse and complex tool kits than small, isolated populations. While several examples of the loss of technology in small populations are consistent with this prediction, it found no support in two systematic quantitative tests. Both studies were based on data from continental populations in which contact rates were not available, and therefore these studies (...) do not provide a test of the models. Here, we show that in Oceania, around the time of early European contact, islands with small populations had less complicated marine foraging technology. This finding suggests that explanations of existing cultural variation based on optimality models alone are incomplete because demography plays an important role in generating cumulative cultural adaptation. It also indicates that hominin populations with similar cognitive abilities may leave very different archaeological records, a conclusion that has important implications for our understanding of the origin of anatomically modern humans and their evolved psychology.

This book is the result of a three-year study undertaken by a multidisciplinary working party of the Institute of Medical Ethic (UK). The group was chaired by a moral theologian, and its members included biological and ethological scientists, toxicologists, physicians, veterinary surgeons, an expert in alternatives to animal use, officers of animal welfare organizations, a Home Office Inspector, philosophers, and a lawyer. Coming from these different backgrounds, and holding a diversity of moral views, the members produced the agreed report as (...) a result of detailed and rigorous discussions. The book sets out facts about animal experiments and about animal abilities to experience pain, distress and anxiety. There is a detailed examination of the moral claims related to the benefits likely to accrue from animal research, and of strategies for weighing these benefits against the harm caused to animals, in order to decide whether particular research projects ought or ought not to proceed. This leads to consideration of the statutory and non-statutory controls which safeguard standards in such research. The final section explores a variety of philosophical arguments about the use of animals in research, and offers a philosophical justification for the Working Party's more practical conclusions. Written in clear, nontechnical language, this book is accessible to lay people as well as to scientists. It is the first such document to emerge from a meeting of people with such widely differing views on this highly controversial subject, and represents a major contribution towards informing and raising the quality of contemporary debate. The book is unique in drawing together material and ideas never before found in one volume. It will interest a broad spectrum of readers, from ethicists and animal rights advocates to scientific researchers and laboratory administrators, along with general readers concerned about this compelling issue.

One of the key learning objectives in any health professional course is to develop ethical and judicious practice. Therefore, it is important to address how medical and pharmacy students respond to, and deal with, ethical dilemmas in their clinical environments. In this paper, we examined how students communicated their resolution of ethical dilemmas and the alignment between these communications and the four principles developed by Beauchamp and Childress. Three hundred and fifty-seven pharmacy and medical students (overall response rate=63%) completed a (...) questionnaire containing four clinical case scenarios with an ethical dilemma. Data were analysed using multiple methods. The findings revealed that 73% of the qualitative responses could be exclusively coded to one of the ‘four principles’ determined by the Beauchamp and Childress' framework. Additionally, 14% of responses overlapped between the four principles (multiple codes) and 13% of responses could not be coded using the framework. The subsequent subgroup analysis revealed different response patterns depending on the case being reviewed. The findings showed that when students are faced with challenging ethical dilemmas their responses can be aligned with the Beauchamp and Childress framework, although more contentious dilemmas involving issues of law are less easily categorised. The differences between year and discipline groups show students are developing ethical frames of reference that may be linked with their teaching environments and their levels of understanding. Analysis of these response patterns provides insight into the way students will likely respond in ‘real’ settings and this information may help educators prepare students for these clinical ethical dilemmas.

BackgroundFindings suggest pandemic control measures have modified maternal health practices, compromising the quality of care provided to new and expectant mothers and interfering with their birthing experiences. For this reason, this study explored the lived experiences of post-partum Victorian mothers during the pandemic as well as the potential influence of control measures over their perceptions regarding the health system.MethodsThis study used a qualitative approach. Recruitment was conducted between May and June 2021, using both the Australian Breastfeeding Association’s social media pages (...) and snowball recruitment. Interviews were semi-structured using open-ended questions relating to key themes. Seven Victorian post-partum mothers were identified and their transcripts analysed using Interpretative Phenomenological Analysis.ResultsMothers described how unexpected changes to maternal care exacerbated feelings of uncertainty regarding pregnancy and birth. Mothers also differentiated between impacts by the health system and the role healthcare professionals played in moderating these effects. Whilst visitor restrictions provided some benefit, restrictions to familial and social support left many of the mothers feeling alone during their pregnancy and interfered with their immediate post-partum experience.ConclusionThis study illustrates the importance of evidence-based practice in maternal care and provides insights for both health professionals and policy analysts in developing new or modifying existing guidelines that better balance the needs of expectant and post-partum mothers with pandemic control measures.

Despite a decade of federal regulation and debate over the appropriateness of financial ties in research and their management, little is known about the actual decision-making processes of university conflict of interest (COI) committees. This paper analyzes in detail the discussions and decisions of three COI committees at three public universities in California. University committee members struggle to understand complex financial relationships and reconcile institutional, state, and federal policies and at the same time work to protect the integrity of the (...) scientific process, the autonomy and intellectual freedom of their faculty colleagues and students, and the financial interests of the university.

It is well-known that naïve realism has difficulty accommodating perceptual error. Recent discussion of the issue has focused on whether the naïve realist can accommodate hallucination by adopting disjunctivism. However, illusions are more difficult for the naïve realist to explain precisely because the disjunctivist solution is not available. I discuss what I take to be the two most plausible accounts of illusion available to the naïve realist. The first claims that illusions are cases in which you are prevented from perceiving (...) properties you would ordinarily perceive and subsequently form a mistaken judgment about the perceived object. The second appeals to an unusual look or appearance that the perceived object instantiates. I argue that neither account is satisfactory and that, consequently, naïve realism ought to be rejected.

Virtually every aspect of the current philosophical discussion of self-deception is a matter of controversy including its definition and paradigmatic cases. We may say generally, however, that self-deception is the acquisition and maintenance of a belief (or, at least, the avowal of that belief) in the face of strong evidence to the contrary motivated by desires or emotions favoring the acquisition and retention of that belief. Beyond this, philosophers divide over whether this action is intentional or not, whether self-deceivers recognize (...) the belief being acquired is unwarranted on the available evidence, whether self-deceivers are morally responsible for their self-deception, and whether self-deception is morally problematic (and if it is in what ways and under what circumstances). The discussion of self-deception and its associated puzzles gives us insight into the ways in which motivation affects belief acquisition and retention. And yet insofar as self-deception represents an obstacle to self-knowledge, which has potentially serious moral implications, self-deception is more than an interesting philosophical puzzle. It is a problem of particular concern for moral development, since self-deception can make us strangers to ourselves and blind to our own moral failings. (shrink)

Jesus instructs us to “love,” “pray for,” and “do good” to enemies, going so far as to make this response to enemies the criterion for being considered “children of your Father in heaven”. Jesus based this instruction on the character of the Father, not on the character of our enemies, which means his instruction allows for no exceptions. In this essay I flesh out the implications of this for a Christian response to terrorism, arguing that this response should look radically (...) different from that of just war theorists. (shrink)

It is widely acknowledged that individual moral obligations and responsibility entail shared (or joint) moral obligations and responsibility. However, whether individual epistemic obligations and responsibility entail shared epistemic obligations and responsibility is rarely discussed. Instead, most discussions of doxastic responsibility focus on individuals considered in isolation. In contrast to this standard approach, I maintain that focusing exclusively on individuals in isolation leads to a profoundly incomplete picture of what we're epistemically obligated to do and when we deserve epistemic blame. First, (...) I argue that we have epistemic obligations to perform actions of the sort that can be performed in conjunction with other people, and that consequently, we are often jointly blameworthy when we violate shared epistemic obligations. Second, I argue that shared responsibility is especially important to doxastic responsibility thanks to the fact that we don't have the same kind of direct control over our beliefs that we have over our actions. In particular, I argue that there are many cases in which a particular individual who holds some problematic belief only deserves epistemic blame in virtue of belonging to a group all the members of which are jointly blameworthy for violating some shared epistemic obligation.

Interpreters of Aquinas’s theory of natural law have occasionally argued that the theory has no need for God. Some, such as Anthony Lisska, wish to avoid an interpretation that construes the theory as an instance of theological definism. Instead Lisska sees Aquinas’s ontology of natural kinds as central to the theory. In his zeal to eliminate God from Aquinas’s theory of natural law, Lisska has overlooked two important features of the theory. First, Aquinas states that the desire for God is (...) a primary precept of the natural law and thus constitutes a critical aspect of his ontology. Secondly, Aquinas’s theory of natural law must be seen in the larger context of his theory of participation since he says, “The natural law is the rational creature’s participation in the eternal law.”.

The Edinburgh Medical Group Research Project is unique in Britain. Part of its function is to experiment with teaching medical ethics both inside and outside of the Medical School. The papers which follow have been written by two full-time reseach fellows working with the Project and two of the professional advisers, one nursing and one medical. Together they give a picture of the wide scope of exerimental teaching taking place in Edinburgh and present some preliminary results from these experiments.

Thanks to the advent of social media, large numbers of Americans believe outlandish falsehoods that have been widely debunked. Many of us have a tendency to fault the individuals who hold such beliefs. We naturally assume that the individuals who form and maintain such beliefs do so in virtue of having violated some epistemic obligation: perhaps they failed to scrutinize their sources, or failed to seek out the available competing evidence. I maintain that very many ordinary individuals who acquire outlandish (...) false beliefs thanks to their use of popular social media platforms (and other similar internet technologies) deserve little or no blame for believing these falsehoods. Such individuals would be fully blameworthy only if they had formed or maintained the relevant beliefs partly in virtue of violating some epistemic obligation and had no excuse for violating that obligation. However, the nature of these internet technologies provides excuses for violating the relevant epistemic obligations, and so individuals are excused for holding the resulting false beliefs. (shrink)

Very often when the vast majority of experts agree on some scientific issue, laypeople nonetheless regularly consume articles, videos, lectures, etc., the principal claims of which are inconsistent with the expert consensus. Moreover, it is standardly assumed that it is entirely appropriate, and perhaps even obligatory, for laypeople to consume such anti-consensus material. I maintain that this standard assumption gets things backwards. Each of us is particularly vulnerable to false claims when we are not experts on some topic – such (...) falsehoods have systematic negative impacts on our doxastic attitudes that we can neither prevent nor correct. So, when there is clear expert consensus on a given scientific issue, while it is permissible for experts to consume anti-consensus material, laypeople have an epistemic obligation to avoid such material. This argument has important consequences for philosophical discussions of our epistemic obligations to perform or omit belief-influencing actions. Such discussions typically abstract away from the important differences between experts and laypeople. Accordingly, we should reject this typical practice as problematic, and insist instead that laypeople and experts have fundamentally different epistemic obligations. (shrink)

Historically, entities with a vested interest in a product that critics have suggested is harmful have consistently used research to back their claims that the product is safe. Prominent examples are: tobacco, lead, bisphenol A, and atrazine. Research literature indicates that about 80–90% of studies with industry affiliation found no harm from the product, while only about 10–20% of studies without industry affiliation found no harm. In parallel to other historical debates, recent studies examining a possible relationship between mercury exposure (...) and autism spectrum disorder show a similar dichotomy. Studies sponsored and supported by industry or entities with an apparent conflict of interest have most often shown no evidence of harm or no “consistent” evidence of harm, while studies without such affiliations report positive evidence of a Hg/autism association. The potentially causal relationship between Hg exposure and ASD differs from other toxic products since there is a broad coalition of entities for whom a conflict of interest arises. These include influential governmental public health entities, the pharmaceutical industry, and even the coal burning industry. This review includes a systematic literature search of original studies on the potential relationship between Hg and ASD from 1999 to August 2015, finding that of the studies with public health and/or industry affiliation, 86% reported no relationship between Hg and ASD. However, among studies without public health and/or industry affiliation, only 21% find no relationship between Hg and ASD. The discrepancy in these results suggests a bias indicative of a conflict of interest. (shrink)

Group beneficial norms are common in human societies. The persistence of such norms is consistent with evolutionary game theory, but existing models do not provide a plausible explanation for why they are common. We show that when a model of imitation used to derive replicator dynamics in isolated populations is generalized to allow for population structure, group beneficial norms can spread rapidly under plausible conditions. We also show that this mechanism allows recombination of different group beneficial norms arising in..

Largely thanks to Mill’s influence, the suggestion that the state ought to restrict the distribution of misinformation will strike most philosophers as implausible. Two of Mill’s influential assumptions are particularly relevant here: first, that free speech debates should focus on moral considerations such as the harm that certain forms of expression might cause; second, that false information causes minimal harm due to the fact that human beings are psychologically well equipped to distinguish truth and falsehood. However, in addition to our (...) moral obligations, we also have a distinct set of epistemic obligations—and even when a false belief doesn’t harm anyone, it constitutes an epistemically bad outcome. Moreover, Mill was profoundly mistaken about human psychology: human beings are vulnerable to the influence of a wide variety of false claims via a wide variety of psychological mechanisms. Consequently, there is a purely epistemic justification for restricting the distribution of misinformation: because each of us has an individual epistemic obligation to avoid unnecessary exposure to misinformation, and because avoiding such exposure is simply too difficult when acting alone, we all have a shared epistemic obligation to establish laws or regulations restricting the widespread distribution of misinformation.

When you have a perceptual experience of a given physical object that object seems to be immediately present to you in a way it never does when you consciously think about or imagine it. Many philosophers have claimed that naïve realism (the view that to perceive is to stand in a primitive relation of acquaintance to the world) can provide a satisfying account of this phenomenological directness of perceptual experience while the content view (the view that to perceive is to (...) represent the world to be a certain way) cannot. I argue that this claim is false. Specifically, I maintain that the only acceptable naïve realist account of the relevant phenomenology is circular and that the content view can provide a similar account. In addition, I maintain that a certain specific variety of the content view provides a non-circular and thus more satisfactory account of this phenomenology. If so, then contrary to what is commonly assumed there are powerful phenomenological grounds for preferring the content view to naïve realism. (shrink)

The philosophical difficulties presented by self-deception are vexed and multifaceted. One such difficulty is what I call the ‘doxastic problem’ of self-deception. Solving the doxastic problem involves determining whether someone in a state of self-deception that ∼p both believes that p and believes that ∼p, simply holds one or the other belief, or, as I will argue, holds neither. This final option, which has been almost entirely overlooked to-date, is what I call ‘ nondoxasticism ’ about self-deception. In this article, (...) I present a negative case for nondoxasticism according to which, in the paradigm case of self-deception, there is no explanatory need to attribute the self-deceived person either their undesired belief that p, or their desired belief that ∼p. Folk psychology is replete with concepts other than belief, and if we bear this in mind, it becomes clear that the explanatory roles for which the self-deceived person's purported beliefs have traditionally been enlisted can be comfortably filled without recourse to belief.

Steve Wilkens edits a debate between three different understandings of the relationship between faith and reason, between theology and philosophy. The three views include: Faith and Philosophy in Tension, Faith Seeking Understanding and the Thomistic Synthesis. This introduction to a timeless quandary is an essential resource for students.

A perceptual experience of a given object seems to make the object itself present to the perceiver’s mind. Many philosophers have claimed that naïve realism (the view that to perceive is to stand in a primitive relation of acquaintance to the world) provides a better account of this phenomenological directness of perceptual experience than does the content view (the view that to perceive is to represent the world to be a certain way). But the naïve realist account of this phenomenology (...) has a conspicuous shortcoming: it explains the phenomenological directness of veridical perceptual experiences but not of hallucinations. Conversely, I maintain that a particular variety of the content view provides a unified account of the phenomenological directness of both veridical and hallucinatory experiences. If so, then contrary to what is often assumed, the phenomenological facts concerning perceptual experience are explained better by the content view than by naïve realism, and consequently, we have a compelling reason to prefer the content view to naïve realism.

Last, in section VI, I explore briefly the existential aspect of Milton’s solution. (shrink)

In recent years, a significant body of literature has emerged on the subject of epistemic injustice: wrongful harms done to people in their capacities as knowers. Up to now this literature has ignored the role that attention has to play in epistemic injustice. This paper makes a first step towards addressing this gap. We argue that giving someone less attention than they are due, which we call an epistemic attention deficit, is a distinct form of epistemic injustice. We begin by (...) outlining what we mean by epistemic attention deficits, which we understand as a failure to pay someone the attention they are due in their role as an epistemic agent. We argue that these deficits constitute epistemic injustices for two reasons. First, they affect someone’s ability to influence what others believe. Second, they affect one’s ability to influence the shared common ground in which testimonial exchanges take place. We then outline the various ways in which epistemic attention deficits harm those who are subject to them. We argue that epistemic attention deficits are harms in and of themselves because they deprive people of an essential component of epistemic agency. Moreover, epistemic attention deficits reduce an agent’s ability to participate in valuable epistemic practices. These two forms of harm have important impacts on educational performance and the distribution of resources. Finally, we argue that epistemic attention deficits both hinder and shape the development of epistemic agency. We finish by exploring some practical implications arising from our discussion.

Early in Plato’s Republic, two cities are depicted, one healthy and one with “a fever”—the so- called luxurious city. The operative difference between these two cities is that the citizens of the latter “have surrendered themselves to the endless acquisition of money and have overstepped the limit of their necessities” (373d).i The luxury of this latter city requires the seizure of neighboring lands and consequently a standing army to defend those lands and the city’s wealth. According to the main character, (...) Socrates, war thus finds its origin in communities living beyond the natural limits of necessity. In short, the healthy or true city is sustainable, limiting its consumption to actual needs, while the luxurious city seems not to be sustainable, living beyond its needs in a perpetual quest for more. Plato spends the rest of the Republic in the attempt to reveal the political organization and virtues—in particular, the virtue of moderation—necessary for the luxurious city to be just, healthy and thereby sustainable. The contrasting images of the two cities and Plato’s subsequent discussion raise important questions about the interrelations between justice, consumption and sustainability. In this paper we appropriate Plato’s images of these metaphorical cities to discuss over-consumption and unsustainable practices by the nations of the contemporary “first world”, which in turn perpetuate poverty and environmental degradation in the nations of the “two-thirds world”. Matters of equity and justice are preeminent in our discussion. (shrink)

The fact that you see some particular object seems to be due to the causal relation between your visual experience and that object, rather than to your experiences’ phenomenal character. On the one hand, whenever some phenomenal element of your experience stands in the right sort of causal relation to some object, your experience presents that object (your experience’s phenomenology doesn’t need to match that object). On the other hand, you can’t have a perceptual experience that presents some object unless (...) you stand in the right sort of causal relation to that object (no matter how closely your experience’s phenomenology matches some object). According to the continuity thesis, property perception is similar to object perception in these two respects. A standard reason to reject the continuity thesis is the assumption that the environmental properties that a perceptual experience presents are determined by its phenomenal properties (which are not determined by the environmental properties that cause the experience). I maintain that the continuity thesis is false but for a different reason: perceptual experiences present both objects and properties via manners of presentation; but, whereas perceptual manners of presentation for objects are purely relational, perceptual manners of presentation for properties are satisfactional.

The reports of individuals who have had their vision restored after a long period of blindness suggest that, immediately after regaining their vision, such individuals are not able to recognize shapes by vision alone. It is often assumed that the empirical literature on sight restoration tells us something important about the relationship between visual and tactile representations of shape. However, I maintain that, immediately after having their sight restored, at least some newly sighted individuals undergo visual experiences that instantiate basic (...) shape phenomenology but which do not present (that is, neither represent nor involve acquaintance with) the corresponding shape properties. Consequently, the empirical literature on sight restoration tells us something important about the role that perceptual phenomenology plays in our perceptual awareness of an object’s properties—it tells us that the properties presented by perceptual experiences are not determined by or “built into” perceptual phenomenology. In addition, I maintain that the evidence concerning sight restoration suggests an alternative theory concerning the role that sensory phenomenology plays in our perceptual awareness of an object’s properties. Specifically, it suggests that, while not inherently representational, sensory phenomenal properties can serve as vehicles for the representation of an object’s properties. (shrink)
